I do know next to nothing about image processing, but I do know something about sunsets/rises (on Earth, of course) and that makes me thinking that maybe the solar panels ARE so reddish when the sun is so low in the sky.

I do know next to nothing about image processing, but I do know something about sunsets/rises (on Earth, of course) and that makes me thinking that maybe the solar panels ARE so reddish when the sun is so low in the sky.

The problem with that is that whereas scattering in Earth's air subtracts blue light, giving red sunsets, on Mars the situation is reversed - Rayleigh scattering is negligible compared with the effect of the suspended dust. The dust filters out red light, giving blue sunsets. Check out that already famous sunset over Gusev image, or more recent ones.

Zvezdichko : I am not using a colorification function in Gimp. It's made from 3 different filters (one neutral,-put in red mode- one green and one blue). The solar pannel look red because of dust accumulation on it accentuated by low sun (not a scattering but a dusty effect) and some frost. Anyway, the colors are not perfect. and after, it's not my target to have the true perfect exact colors (for me it's an affair of interpretation).

In the attachment you will find a highly reduced version created with a white pointing with the level tool (white pointing made on a place on the solar pannel). I find this version too greenish in some place.

I don't know exactly. He read the IMG file in 16 bits format. But the PNG exportation is made in 8 bits. But there is various format of exportation like tiff, jpeg, fits, bmp, etc.Tiff is the only one to be in 16 bits, but it's lead to have a very dark picture. I think there is some settings to make to have a brighter pic.
